A recently-released study of sea level rise measured by satellite altimetry shows a troubling hint of an accelerating upward trend in the already rising sea levels which may mean that coastal areas could be swamped sooner and more frequently than was previously predicted.  You can read the original paper in Nature‘s Scientific Reports  at https://www.nature.com/articles/srep31245.

The Washington Post wrote a more descriptive article here which shows how the eruption of Mount Pinatubo in 1992 artificially masked the sea level rise by providing a few years of global cooling (which is common after strong volcanic eruptions but does not affect long-term climate trends).
